Limits
This topic describes the feature limits for IoT Edge instances.
General limits
Limit item | Description | Limit |
Number of devices connected to an edge appliance | The maximum number of video devices that can be connected to a single edge appliance. Note Due to the computing power limits of edge appliances, the number of video devices that can be connected varies by appliance. For more information, see the user manual provided with your edge appliance. | Determined by the edge appliance model. |
The maximum number of general-purpose devices that can be connected to a single edge appliance. Note General-purpose devices must be connected to the edge appliance through a driver. | 1500 | |
The maximum number of drivers that can be connected to a single edge appliance. | 30 | |
Default ports used by the edge appliance | When planning applications, avoid the host ports that are used by the base services of the appliance by default. |
|
Binary runtime edge appliances
Limit item | Description | Limit |
Number of containerized applications | Containerized applications cannot be installed or used on a binary runtime edge appliance. | Not applicable. |
Number of process-based applications | The maximum number of process-based applications that can be installed and activated on a single binary runtime edge appliance. | 30 |
Container runtime edge appliances
Limit item | Description | Limit |
Number of containerized applications | On a container runtime edge appliance, there is no limit on the number of containerized applications. However, there are limits on the total CPU and memory that can be used by these applications. Note Containerized applications must not use the CPU and memory resources that the edge appliance host requires to run. For information about the required host resources, see the user manual provided with your edge appliance. | No specific limit. The number is determined by the remaining CPU and memory of the edge appliance. |
Number of process-based applications | The maximum number of process-based applications that can be installed and activated on a single container runtime edge appliance. | 30 |
Default CIDR blocks used | Default host IP addresses that are used. |
|
The default host CIDR block and the virtual CIDR block for the container service. Resources in these blocks can access each other by name. |
